one of the things thalt obama campaign says is that they feel that barack obama -- rather mitt romney made a big mistake by not talking more specifically about his plan. they say barack obama won't make that same mistake in his speech and he will speak in great detail about where he would take the country. they have laid out a set of goals. here's the problem. i brought with me a copy of the speech that barack obama made four years ago, during the convention in 2008 and an awful lot of what you are going to hear sounds awfully familiar to what he said four years ago. tonight, you are going to hear barack obama say he wants to cut net oil exports in half, or imports, rather, in half by 2020. well, four years ago, he promised to end the dependence on mid-east oil by 2018. tonight he is going to talk about recruiting 100,000 math and science teachers. four years ago, he promised to recruit an army of new teachers. an awful lot of you what are going to hear is recycled. but conspire -- for someone so concerned about the environment, that's a good thing. >> chris wallace, thank you. >> mar
